Debian DLA-624-1 : mysql-5.5 security update

critical Nessus Plugin ID 93564

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Dawid Golunski discovered that the mysqld_safe wrapper provided by the MySQL database server insufficiently restricted the load path for custom malloc implementations, which could result in privilege escalation.

The vulnerability was addressed by upgrading MySQL to the new upstream version 5.5.52, which includes additional changes, such as performance improvements, bug fixes, new features, and possibly incompatible changes. Please see the MySQL 5.5 Release Notes for further details :

https://dev.mysql.com/doc/relnotes/mysql/5.5/en/news-5-5-51.html https://dev.mysql.com/doc/relnotes/mysql/5.5/en/news-5-5-52.html

For Debian 7 'Wheezy', these problems have been fixed in version 5.5.52-0+deb7u1.

We recommend that you upgrade your mysql-5.5 packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
